Which graph best represents a function with zeros of -4, -2, and 4?
Answer:
D.
Step-by-step explanation:
The line goes through those points
The polynomail that represents the graph will be g(x) = (x + 4)(x + 2)(x - 4). Then the correct option is D.
How to get polynomials with zeroes?Let a, b, c, and d are the zeroes of the polynomial.
Then the polynomial is given as,
⇒ (x - a)(x - b)(x - c)(x - d)
The degree of the polynomial will be greater than or equal to the number of zeroes.
The zeroes of the function are -4, -2, and 4. Then the factor of the equation is given below.
x = - 4
x + 4 = 0
x = -2
x + 2 = 0
x = 4
x - 4 = 0
Then the polynomial is given below.
g(x) = (x + 4)(x + 2)(x - 4)
The polynomail that addresses the chart will be g(x) = (x + 4)(x + 2)(x - 4). Then the right choice is D.

N
Answer:
[tex]NO= 31.2[/tex]
Step-by-step explanation:
See attachment for triangle
From the attachment, we have:
[tex]KL = 51.6[/tex]
[tex]LM= 38[/tex]
[tex]OP = 23[/tex]
Required
Find NO
This will be calculated using the following equivalent ratios:
[tex]NO : OP = KL : LM[/tex]
This gives:
[tex]NO : 23= 51.6: 38[/tex]
Express as fraction
[tex]\frac{NO }{ 23}= \frac{51.6}{ 38}[/tex]
Make NO the subject
[tex]NO= \frac{51.6}{ 38} * 23[/tex]
[tex]NO= \frac{51.6* 23}{ 38}[/tex]
[tex]NO= \frac{1186.8}{ 38}[/tex]

Car X travels 174 miles in 3 hours.
Answer:
The graph =
y = 58xStep-by-step explanation:
(a)
distance covered (y) = 174 miles
time taken (x) = 3 hours
Therefore the points = (3, 174) and (0, 0) = stationary position
Find the gradient (m)
m = 174-0 / 3-0
m = 58
Therefore the equation =
y = 58x(distance = 58 × time)
For the distance = 174 and time = 3 hours, the equation to find either distance or time = y = 58x
(b) the graph is constant, because the time and distance are also contant when the speed used is the same.

The image below shows four soccer balls at different
locations on an uneven soccer field. Which ball has the
greatest amount of kinetic energy? Explain your answer.
Answer: letter d
Step-by-step explanation:
Answer:
Ball D. Among the four balls in this picture, ball D is the only one whose kinetic energy is greater than [tex]0[/tex].
Step-by-step explanation:
Consider an object of mass [tex]m[/tex]. If this object is moving at a speed of [tex]v[/tex], the kinetic energy of this object would be:
[tex]\displaystyle \frac{1}{2}\, m \cdot v^{2}[/tex].
The speed [tex]v[/tex] of ball A, B, and C are all [tex]0[/tex]. Hence, the kinetic energy of these three balls would be [tex]0\![/tex].
The speed of ball D is greater than [tex]0[/tex]: [tex]v = 2\; \rm m \cdot s^{-1}[/tex]. The kinetic energy of this ball would be:
[tex]\begin{aligned} {\rm KE} &= \frac{1}{2}\, m \cdot v^{2} \\ &= \frac{1}{2}\times \rm 0.43\; \rm kg \times \left(2\; \rm m \cdot s^{-1}\right)^{2}\\ &= 0.86\; \rm J\end{aligned}[/tex].
Hence, the kinetic energy of ball D is the greatest among the four balls in this picture.

A soft-drink machine is regulated so that the amount of drink dispensed is approximately normally distributed with known standard deviation, sigma. Given a random sample of n drinks and the sample mean, x-bar, you find a 90% confidence interval for the mean of all drinks dispensed by this machine. Then you calculate a 90% confidence interval (same confidence level) using a larger sample, for example (n 20) drinks. Also, you notice that the sample mean, x-bar, is the same for both samples.
Required:
Was this a reasonable decision?
Answer:
This is a reasonable decision because the sample size has no effect on the 90% confidence interval
Step-by-step explanation:
90% confidence interval
larger sample size = 20
condition : sample mean ( x-bar ) is the same for both samples
This is a reasonable decision because the sample size has no effect on the 90% confidence interval
from condition 1 :
Amount of drink dispensed is normally distributed with known standard deviation , given a random sample of n drinks and the sample mean at a confidence interval of 90%
for condition 2 :
sample size = 20
mean = 2.25 ( assumed value )
std = 0.15 ( assumed value )
Z = 1.645 ( Z-value )
determine the 90% confidence interval
= mean ± z [tex]\frac{std}{\sqrt{n} }[/tex]
= 2.25 ± 1.645 [tex]\frac{0.15}{\sqrt{20} }[/tex]

I am trying to solve this but I don't understand.
Answer:
a = 42 b = 21
Step-by-step explanation:
a is 42 since it ks vertically opposite 42
To solve for b
360 - (42×2)........to get the angle next to a
=276... Divde answer by 2. Bc there are two of the angles
276÷2 =138
138 + 2b =180
2b = 180 - 138
b = 42 ÷ 2
b = 21
Find the lateral surface area of
the following cylinder:
r = 5 cm
5 cm
LSA= [ ? ]n cm?
Leave your answer in terms of T.
Enter the number that goes in the green box.
Answer:
50π cm²
Step-by-step explanation:
Lateral surface area of a cylinder is the area surrounding curved surface of the cylinder
Thus:
Lateral surface area of the cylinder = 2πrh
Where,
r = 5 cm
h = 5 cm
Plug in the values
Lateral Surface Area = 2*π*5*5
= 50π cm²
